Matters of Faith | memorious
That is not news. Nor is it unique to fields that study things like gender and race, as opposed to, say, mathematics and engineering — two areas recently subjected to a hoax that placed 120 AI-generated nonsense papers (which should, presumably, have been even easier for educated eyes to spot than the hand-crafted junk submitted here) in journals. Every field can be hoaxed, and many have been. But only some fields can be hoaxed profitably. There is no built-in audience of people who despise mathematics and applaud when mathematicians get pranked. But there is a large audience, in social and traditional media, primed for the humiliation of “left-wing”, and especially “feminist”, scholars. If one wanted to establish something about the relative intellectual legitimacy of gender studies and, say, economics, or engineering, or physics, one could presumably try to fool reviewers in each, see who did better, and figure out why. That didn’t happen here, because the point wasn’t to conduct any such study. It was to embarrass a target. (That they labelled all the fields concerned dismissively as “Grievance Studies” is just the crassest evidence of parti pris.)

The Galileo Circus is in town | The Renaissance Mathematicus
Before I go on I think it is necessary to restate something that people discussing the situation tend to forget or ignore. In the early seventeenth century the concepts of freedom of thought, freedom of speech and freedom of expression simply did not exist anywhere in Europe neither under secular or religious jurisdiction, no matter which church was involved. This was something that Galileo was well aware of but apparently in his hubris he thought his newly found fame would protect him from censure, he was wrong. A second point that also tends to get ignored is that when Galileo decided to go into full frontal attack with the Church on scriptural interpretation it was the middle of the Counter Reformation. The Reformation and the Counter Reformation centred on the question, who is allowed to interpret Holy Scripture. The Lutherans said anybody who could read, although they later changed their minds on that, whereas the Catholic Church said only the Church theologian were entitled to. Here was Galileo a mere mathematicus, the lowest of the low in the Renaissance intellectual hierarchy, telling the theologians, the pinnacle of the Renaissance intellectual pyramid, how to interpret the Bible, not a wise move. Not only did Galileo go out on a limb but he did so with his very best polemic and invective and if there was something in which Galileo was unrivalled at it was writing polemic and invective.

Not a martyr for science. | The Renaissance Mathematicus
The discovery of pulmonary circulation actually got lost at least twice and Servetus was not its first discoverer. Pulmonary circulation had already been discovered in the thirteenth century by Ala-al-din abu Al-Hassan Ali ibn Abi-Hazm al-Qarshi al-Dimashqi, known as Ibn al-Nafis, and published in his Commentary on the Anatomy of Canon of Avicenna a text that simply disappeared and was first re-discovered in the twentieth century. Somehow this was a discovery that didn’t want to be made. However pulmonary circulation was discovered independently for a third time, and this time demonstrated empirically, by Realdo Colombo, Vesalius’ successor as professor of anatomy in Padua, in 1559 and this time it remained discovered.

Scientific Autonomy, Public Accountability, and the Rise of “Peer Review” in the Cold War United States | Isis: Vol 109, No 3
This essay traces the history of refereeing at specialist scientific journals and at funding bodies and shows that it was only in the late twentieth century that peer review came to be seen as a process central to scientific practice. Throughout the nineteenth century and into much of the twentieth, external referee reports were considered an optional part of journal editing or grant making. The idea that refereeing is a requirement for scientific legitimacy seems to have arisen first in the Cold War United States. In the 1970s, in the wake of a series of attacks on scientific funding, American scientists faced a dilemma: there was increasing pressure for science to be accountable to those who funded it, but scientists wanted to ensure their continuing influence over funding decisions. Scientists and their supporters cast expert refereeing—or “peer review,” as it was increasingly called—as the crucial process that ensured the credibility of science as a whole. Taking funding decisions out of expert hands, they argued, would be a corruption of science itself. This public elevation of peer review both reinforced and spread the belief that only peer-reviewed science was scientifically legitimate.

What Is Threatening Science? by Jeremy J. Baumberg - Project Syndicate
Globalization, the digitization of knowledge, and the growing number of scientists all seem, at first glance, like positive trends for the progress of science. But these trends are Janus-faced, for they also encourage a hyper-competitive, trend-driven, and herd-like approach to scientific research.

Today in something is wrong on the Internet | The Renaissance Mathematicus
When I was growing up one of the most widespread #histSTM myths, along with the claim that people in the Middle Ages believed the world was flat and Stone Age people lived in holes in the ground, was that Galileo Galilei invented the telescope. This myth actually has an interesting history that goes all the way back to the publication of the Sidereus Nuncius. Some of Galileo’s critics misinterpreting what he had written asserted that he was claiming to have invented the telescope, an assertion that Galileo strongly denied in a latter publication. Whatever, as I said when I was growing up it was common knowledge that Galileo had invented the telescope. During the 1960s and 1970s as history of science slowly crept out of its niche and became more public and more popular this myth was at some point put out of its misery and buried discretely, where, I thought, nobody would find it again. I was wrong.

The last polymath
Historian David Cahan copes confidently with these complexities in his monumental new biography. The result of almost three decades of scholarly work, Helmholtz is a comprehensive and timely account. In recent years, historians of science have published several studies devoted to isolated aspects of Helmholtz’s work — his contributions to neurophysiology and hydrodynamics, as well as his epistemology and aesthetics.

However, anyone interested in the complete picture was forced to go back more than 100 years, to a bulky biography by German mathematician Leo Königsberger. In no fewer than three volumes published in 1902–03, Königsberger, a friend of the Helmholtz family, depicted the German scholar as a lonesome genius whose scientific success was the result of unusual giftedness combined with extremely hard work.

Helmholtz is an impressive corrective to such partial or simplistic treatments. The book not only accounts for the German scholar’s voluminous publications (his Lectures on Theoretical Physics alone comprise six volumes, posthumously published between 1897 and 1907), but also encompasses an uncounted number of manuscripts and letters dispersed in archives all over the world. The result is as compelling as it is convincing.

Victorian Doctors Didn't Treat Women With Orgasms, Say Historians - The Atlantic
It’s not hard to see how the idea spread. The entire story of Victorian vibrators originates from the work of one scholar: Rachel Maines, a historian and a former visiting scientist at Cornell University. Her 1999 book, The Technology of Orgasm—described at the time as a “secret history of female sexual arousal”—argued that clitoral massage was used as a medical technique for centuries, from the time of Hippocrates to the modern day.

But that’s just not true, according to Lieberman and Eric Schatzberg, the chair of the School of History and Sociology at Georgia Tech. There is scant evidence that orgasms were widely understood as a cure for female hysteria, and there’s even less evidence that Victorians used vibrators to induce orgasm as a medical technique, they say. “Maines fails to cite a single source that openly describes use of the vibrator to massage the clitoral area,” their paper says. “None of her English-language sources even mentions production of ‘paroxysms’ by massage or anything else that could remotely suggest an orgasm.”

Instead, they argue, Maines conceals this lack of support by relying on a “wink and nod” approach to primary sourcing and by “padding her argument with a mass of tangential citations.”

Hasok Chang, Anti-Alchemist | Forbidden Histories
I have shown this experiment to dozens of professional chemists and chemistry students. There hasn’t been a single person not surprised to see gold dissolved in salt water with the help of mere 3 volts of electricity. The kinds of things I was looking into, arising from my work in the history of science, are quite far from cutting-edge issues in today’s chemistry. It was surprising to me that none of the chemists I spoke to had ever conducted this experiment before — but then again, why would they? Perhaps I have a heretical sense of what scientists ought to be attending to.

I have a lot more work to do. As yet I don’t know the exact identity of that yellow streak that comes off the gold electrode. It must be some sort of gold chloride, but an exact analysis will need to be performed. I also don’t know why the reaction happens only in a narrow range of voltages applied. I am not a chemist, and my chemist colleagues at the Universities of London, Cambridge and elsewhere have not had ready answers to all of my questions. But I hope they will continue to help me in my research.

The war over supercooled water
The procedure the Berkeley team used to initialize the molecular dynamics simulations was unorthodox—it involved randomly selecting a pair of molecules and then swapping their velocities. Palmer and company discovered that the technique produced sample configurations that seemed to flout basic laws of statistical mechanics: The energies deviated from the expected equilibrium values, governed by the Boltzmann distribution, and the molecules’ rotational and translational temperatures didn’t match up. Perhaps most important, the molecules behaved as if they were tens of degrees hotter than their assigned temperature.

Suddenly it made sense that the Berkeley researchers hadn’t seen a second liquid phase; they were effectively running their simulations at temperatures well above the critical point. The moment the Princeton group swapped out the unorthodox sampling scheme with a standard one, the discrepancy went away.

Entropy Explained
You might’ve heard an explanation that goes like this: whenever you drop an egg, or melt an ice cube, or shatter a wine glass, you’ve increased the entropy of the world. You might also have heard the phrase, “entropy always increases”. In other words, things are only allowed to happen in one direction — the direction in which entropy increases.

But this doesn’t answer the question, it just replaces it with a new set of questions.

What is entropy, really? Why does it always keep increasing? Why don’t eggshells uncrack, or wine glasses unshatter? In this piece, my goal is to give you the tools to answer these questions.

Backreaction: Evidence for modified gravity is now evidence against it.
Indeed, it would be an interesting exercise to quantify how well modified gravity does in this set of galaxies compared to particle dark matter with the same number of parameters. Chances are, you’d find that particle dark matter too is ruled out at 5 σ. It’s just that no one is dumb enough to make such a claim. When it comes to particle dark matter, astrophysicists will be quick to tell you galaxy dynamics involves loads of complicated astrophysics and it’s rather unrealistic that one parameter will account for the variety in any sample.

Without the comparison to particle dark matter, therefore, the only thing I learn from the Rodrigues et al paper is that a non-universal acceleration scale fits the data better than a universal one. And that I could have told you without even looking at the data.

Summary: I’m not impressed.

It’s day 12,805 in the war between modified gravity and dark matter and dark matter enthusiasts still haven’t found the battle field.

The Case of Verge Genomics | In the Pipeline
Ash Jogalekar summed it up perfectly on Twitter yesterday, as shown at right. The problems with Alzheimer’s, ALS, and Parkinson’s drug discovery are not data handling problems. The important problems with drug discovery in general are not data handling problems, and unfortunately there are many people who would like to think that they are. Who would perhaps like to think that everything could be solved if we could just obtain and correlate enough data. But what we’re short of is insights, ideas, and understanding, and those come slowly, painfully, and expensively.

The Hunt for Earth’s Deep Hidden Oceans | Quanta Magazine
tl,dr: how to get samples from inaccessible places
These mineral flecks — some too small to see even under a microscope — offer a peek into Earth’s otherwise unreachable interior. In 2014, researchers glimpsed something embedded in these minerals that, if not for its deep origins, would’ve been unremarkable: water.

Not actual drops of water, or even molecules of H20, but its ingredients, atoms of hydrogen and oxygen embedded in the crystal structure of the mineral itself. This hydrous mineral isn’t wet. But when it melts, out spills water. The discovery was the first direct proof that water-rich minerals exist this deep, between 410 and 660 kilometers down, in a region called the transition zone, sandwiched between the upper and lower mantles.

Association of Type 2 Diabetes with Submicron Titanium Dioxide Crystals in the Pancreas - Chemical Research in Toxicology (ACS Publications)
Inhaled and ingested submicron and micron-sized crystals and crystal aggregates are associated with chronic inflammatory degenerative diseases. Diseases of the lung, exemplified by silicosis and asbestosis, result of inhalation of crystalline silica and asbestos. Crystals of sodium urate, cystine, calcium oxalate dihydrate and calcium pyrophosphate dihydrate are associated with chronic inflammatory degenerative diseases of the joints, kidneys, and urinary tract.
Pigment-grade TiO2, typically of rutile phase and of 200–300 nm particle diameter, about half the wavelength of visible light, is widely used. Because of its 2.6 index of refraction, it constitutes the dominant light-scattering, that is, “white” component of indoor wall paints, drinks, foods, toothpastes, medications, cosmetics, paper, and plastics. The annual production of pigment-grade TiO2 has increased in the past 50 years from 2 × 106 tons to 6 × 106 tons, as TiO2 replaced the earlier used, more toxic, lead carbonate white pigment. Consumers and patients are routinely exposed to TiO2 crystals, inhaling and ingesting these.

Richard Smith: Medical research—still a scandal - The BMJ
Twenty years ago this week the statistician Doug Altman published an editorial in the BMJ arguing that much medical research was of poor quality and misleading. In his editorial entitled, “The Scandal of Poor Medical Research,” Altman wrote that much research was “seriously flawed through the use of inappropriate designs, unrepresentative samples, small samples, incorrect methods of analysis, and faulty interpretation.” Twenty years later I fear that things are not better but worse.

Backreaction: The Multiworse Is Coming
It’s a PR disaster that particle physics won’t be able to shake off easily. Before the LHC’s launch in 2008, many theorists expressed themselves confident the collider would produce new particles besides the Higgs boson. That hasn’t happened. And the public isn’t remotely as dumb as many academics wish. They’ll remember next time we come ask for money.

The big proclamations came almost exclusively from theoretical physicists; CERN didn’t promise anything they didn’t deliver. That is an important distinction, but I am afraid in the public perception the subtler differences won’t matter. It’s “physicists said.” And what physicists said was wrong. Like hair, trust is hard to split. And like hair, trust is easier to lose than to grow.

This is news to me…though maybe not to you.  Since I first read about the Pygmalion effect as a first-year college student I ‘ve bored countless friends and acquaintances with this study.  It was a conversational lodestone; I could find expectancy effects everywhere and so talked about them frequently.  No more, or at least not nearly so simplistically.  The original Pygmalion Effect is seductive baloney.

What has really crushed my spirit today is the history of the Pygmalion Effect.  It turns out that when it was published it set off a wave of debate that very closely mirrors the current replication crisis.  Details are below, but here’s the gist:

Dragonfly - Dunlap Institute
Dragonfly is an innovative, multi-lens array designed for ultra-low surface brightness astronomy at visible wavelengths. Commissioned in 2013 with only three lenses, the array is growing in size and proving capable of detecting extremely faint, complex structure around galaxies. The most recent upgrade—completed in 2016—saw Dragonfly grow to 48 lenses in two clusters.

Dragonfly is designed to reveal the faint structure by greatly reducing scattered light and internal reflections within its optics. It achieves this using commercially available Canon 400mm lenses with unprecedented nano-fabricated coatings with sub-wavelength structure on optical glasses.

Mythical Retention Data & The Corrupted Cone – Work-Learning Research
I include these two examples to make two points. First, note how one person clearly stole from the other one. Second, note how sloppy these fabricators are. They include a Confucius quote that directly contradicts what the numbers say. On the left side of the visuals, Confucius is purported to say that hearing is better than seeing, while the numbers on the right of the visuals say that seeing is better than hearing. And, by the way, Confucius did not actually say what he is being alleged to have said! What seems clear from looking at these and other examples is that people don’t do their due diligence—their ends seems to justify their means—and they are damn sloppy, suggesting that they don’t think their audiences will examine their arguments closely.

If I can stay awake at night freaking out about the EPR paradox and the foundations of quantum mechanics, you damn well can too. Seriously.

"I placed too much faith in underpowered studies:" Nobel Prize winner admits mistakes - Retraction Watch at Retraction Watch
Although it’s the right thing to do, it’s never easy to admit error — particularly when you’re an extremely high-profile scientist whose work is being dissected publicly. So while it’s not a retraction, we thought this was worth noting: A Nobel Prize-winning researcher has admitted on a blog that he relied on weak studies in a chapter of his bestselling book.

The blog — by Ulrich Schimmack, Moritz Heene, and Kamini Kesavan — critiqued the citations included in a book by Daniel Kahneman, a psychologist whose research has illuminated our understanding of how humans form judgments and make decisions and earned him half of the 2002 Nobel Prize in Economics.
